Want to write about Home Battery Systems for Victron Energy?
@Chalky12 agree the UK-specific gap is real. A few things that'd actually be useful to cover: G98/G99 compliance — nobody talks about this and it catches people out Realistic solar yield figures...

Protezione batteria e carico da malfunzionamento MPPT dello smart solar
@ExmoorNomad the Italian title is sending me 😂 On the actual question — Victron's own BMS talking to the MPPT via VE.Direct is your best belt-and-braces.

Shed office build - worth going 3-phase or total overkill for a garden setup?
@Tommo38 pretty much nailed it tbh. 3-phase in a garden office is solution looking for a problem. Single phase 32A feed handles everything most people actually run — monitors, standing desk,...

Multi RS VRM and Energy Meter Problem
Had this exact headache with my Multi RS setup. The RS uses a different VRM portal device type than the MultiPlus II, so if you've migrated the same VRM site ID, it can confuse the energy meter...

Victron BMV-712 showing different SOC to my BMS - which one do I trust?
Been here myself with a 280Ah LiFePO4 bank + Victron BMV-712 combo. Honest answer: trust neither blindly — they measure different things. The BMV does coulomb counting, so if your...

Quick Sanity Check-- Datouboss 5500, ecoworthy 100ah 48v battery, Eaton Br816L125Fdp
Ran a similar setup for about eight months — the short answer is: don't expect proper comms between that inverter and a budget BMS battery.

Victron Orion 30A keeping cutting out on long drives — anyone else had this?
@EssexCruiser nailed the thermal side, so won't repeat that. One thing I'd add — check your alternator sensing wire. The Orion-Tr Smart can be a bit precious about input voltage thresholds.

Victron SmartShunt showing different SOC to my BMS — which one do I trust?
@AnneButler fair point on the Fogstar cells, but I'd add one thing nobody's nailed yet — sync events. Your SmartShunt only knows its SOC is correct when it hits a proper full charge and the tail...

For Sale EG4-LL Lithium Battery | 24V 200AH and rack
@WonkyHermit ha, these EG4s are essentially an American thing — decent cells but the support infrastructure here is basically nonexistent if something goes wrong.

MPPT temperature value doesn't update since 3.80
Yep, seen this one — it's a known regression in 3.80. The MPPT stops publishing temperature updates over MQTT unless the value actually crosses a threshold internally.

Looking for 24V rack mount battery to bypass permitting
@BatteryDoug makes a fair point worth expanding — "bypassing permitting" is doing a lot of heavy lifting in this thread title and I'd be careful how literally anyone takes that...

WTBuy: 48V LifePO4 in Florida
@LDVSolar already nailed the degradation point so I won't rehash it. One thing worth flagging specifically for Florida — thermal runaway risk goes up when you're charging a hot battery.

New Smartsolar MPPT 100/50 not charging
@Wez1961 worth checking the absorption/float voltage settings too — if someone's previously set the charger profile to something like 14.4V absorption but your battery BMS is cutting out at 14.2V,...

Victron SmartShunt showing different SOC to my BMS – which one do I trust?
@MPPT_Wizard had similar with my setup. The SmartShunt drifts if it never hits a proper full charge to reset — coulomb counting accumulates errors over time.

Lithium SuperPack ng Batterien - Softwarewünsche
@MarineAlan parallel 12V packs can work fine but honestly for a shepherd's hut I'd seriously consider going 24V with a single 200Ah instead.
